This invention relates to a molded shoe such as are custom made to titan individuals feet and more particularly to an improvement in custommolded shoes wherein a sponge rubber sole element is retainedperipherally by a semi-rigid cavity containing element.

A conventional practice in the shoe art is to apply a sponge rubbersheeting or pad as the top element of the insole and against which thefoot of the wearer rests.

The Weight of the wearer on the sponge rubber pad squashes it, causing alateral movement of the material. In due time, the sponge rubber padloses its resilience or rebound qualities and for all practical purposesfunctions no longer as sponge rubber.

According to this invention, the sponge rubber pad is retained incaptive relationship in a molded cavity of a relatively dexiblecomposition.

It is an object of this invention to provide a sponge rubber footengaging pad adapted to retain substantially permanent resiliency.

It is another object to provide a shoe having a sponge rubber sole padretained permanently in captive relationship in a flexible sole.

It is a further object to provide a shoe having comfortable resiliencythroughout the life of the shoe.

These and other objects of this invention will become apparent uponreaching the following descriptive disclosure taken in conjunction withthe accompanying drawing of an illustrative embodiment in which:

FIG. 1 is a side elevation view of the shoe,

FIG. 2 is a longitudinal section view of the shoe showing theconstruction thereof, and

FIG. 3 is a section view taken on line 3 3 of FIG. l.

Turning to the drawing, the shoe of this invention is constructed byfirst making separate plaster casts of the customers two feet.

Next, the plaster cast is covered with suitable stocking material andtwo ply monks cloth 11 is secured thereto by conventional all purposelatex cement. Next a suitable cord of cotton or the like 12 is suitablylocated substantially toe high peripherally about the cast and adheredto the monks cloth by use of said cement.

Next, suitably thick sponge rubber padding 13 made of synthetic ornatural rubber, is cut to the shape of the sole and its peripheral edgesare tapered by means of a sharp knife.

The shaped sponge rubber pad is then adhered to the monks cloth by meansof said cement and the edges thereof are made to engage said cord 12 andadhere thereto by means of said cement.

Next, a single ply monks cloth 14 is adhered to the outer surface of thesponge pad also by means of said cement.

cork or Wood flour is mixed with a conventional solvent containing latexcomposition and the mixture is then applied to the single ply monkscloth by means ot a spatula to form a cavitated element which upondrying is ilexible and adhesively secured to said monks cloth. Thus theshaped sole sponge pad is captively disposed in a cavitated exible soleelement 15 of relatively rigid composition. Thus the combination of sole13 and composition elernent 15 is novel and provides sponge resiliencyin the shape retaining ilexible cavity containing element 15.

Next, a suitably wedge shaped heel element 16 cut from suitablerelatively rigid sheet rubber is secured by said cement to said cavityelement i5. Next a heel textile fabric 1S is secured about the theel bymeans of said cement. Then a lining of tine quality leather 19 isadhesively secured about the upper exposed area of the shoe by means ofsaid cement. And lastly a suitable wearing sole 2t) of exteriorlycorrugated rubber sheet is secured to the bottom of the shoe by saidcement.

The molded shoe is then removed from the plaster cast by breaking thecast with suitable blows of a hammer.

Such a shoe is comfortable throughout its life since the sponge rubberinsole 1 3 is fenced in and united to a resilient boat-like element 15.

This invention is disclosed by a specific embodiment illustrating thenovel concept, which concept is oi' generic scope as claimed herein.

I claim:

A custom made shoe comprising a first layer cloth insole having a footshaped toe high cavity having a base portion therein; a flexible corddisposed peripherally about said insole and adhesively secured thereto;a second sponge rubber insole tapered at its edge secured adhesively tosaid cloth insole with .the tapered edge engaging said cord; a thirdinsole layer of cloth secured adhesively to said rubber insole; ailexible latex composition containing cork ller adhesively disposed ontosaid third layer of cloth; a wedge shaped flexible rubber heeladhesively secured to said flexible latex composition; exterior liningmeans adhesively secured to said insoles to form the rupper portion ofsaid shoe and a lrubber wearing exterior sole adhesively secured to saidlatex composition at the front ofthe shoe and to said heel.
